British Jewish Community Gravitating to Green Party and Reform Party as Backing for Main Parties Falls

Research has uncovered a fresh electoral split across British Jews, with backing growing quickly for the Greens – propelled by youthful and “anti-Zionist” Jews – while more senior Orthodox men lean toward Reform UK as confidence in the dominant political groups “plummets”.

Backing of the Conservative and Labour parties among UK Jewish voters had fallen to 58% by July 2025 from almost 84% in 2020, based on a report from a prominent policy organization, which commented it was “the weakest support we’ve ever recorded by some distance”.

Labour is typically preferred by more “secular” Jews while the Conservative party is conventionally preferred by more “religious” Jews.

Meanwhile, almost 18% of British Jews (18%) were supporting the Green party by June 2025 – which researchers described as “surprising” given its position on the Israeli state, which it described an “discriminatory system” in a resolution at its 2024 party conference.

Approval of the Green Party rose 9% among the Jewish community between the summer 2024 election and June 2025, outstripping the 1% rise in Green support among the general public over the equivalent interval, and predating the guidance of a prominent politician who describes himself as a “committed” Jew but “non-Zionist”.

The report stated the rise in Green Party support implied “for a notable portion of Jews, national issues and progressive values outweigh foreign policy concerns”.

In contrast, support for Reform grew among the Jewish community from 3% in summer 2024 to 11% in June 2025. But the increase lagged the 14% rise Reform experienced with the wider electorate.

“Jewish voters are less inclined [than the general population] to vote for Reform [11% vs 28%], but more prone to vote for the Green party [18% vs 7%],” the report said.

A prominent expert remarked: “The Reform Party is more prone to attract men, elderly, orthodox, and pro-Israel Jews; the Green Party are more prone to attract youthful, non-religious and anti-Israel …[but] it is essential to note that it is also an element of a larger, broader shift affecting the UK population as a whole.”

Nonetheless, the “rapid increase in backing from Jews for Reform – a party whose language on migration and national identity would normally be expected to alienate ethnic groups, like Jews” was labeled “remarkable” by the study.

“Notable portions of the Jewish community may move toward voices pledging firmness and certainty, irrespective of ideological baggage” when traditional groups were viewed as “indecisive or hostile”, it added.

The analysis declared: “For the initial instance in contemporary British Jewish experience, support for the two main parties combined has fallen below 60%.

“Given that this is mirrored in wider society too, it is not just a numerical irregularity – it may indicate a fundamental change in the political views of Jews.

“Three forces are propelling this splintering: the Gaza conflict and its splitting influence on community views; rising antisemitism, culminating in a major terrorist attack at a Jewish house of worship; and a broader loss of confidence in mainstream parties.

“Collectively, these elements are guiding Jews in the direction of parties that offer certainty – whether through mass rhetoric or radical progressivism.

“If current trends continue … the UK Jewish community are expected to become more politically polarised, prompting further internal community tensions.”

The organization, which tracks community changes, polled 11,000 British Jews for the study, called The end of two-party politics? Recent shifts in the electoral choices of UK Jewish voters.

It found that in the election year, Jewish voters were more inclined than the general population to back the two main parties, with 44% backing the Labour Party, versus 34% of the general public, and 32% supporting Conservative, versus 24% of the general population.

By mid-year, backing of the Labour Party had slumped by 13% among UK Jewish voters, against a 9% decline with the general public, while backing for the Conservatives among the Jewish community dropped by 4%, matching the broader population. “Minimal and steady” approval of the Lib Dems has changed from 8% to 9% among UK Jewish voters.
